Transformer are the static electrical device which transmit the power at different voltage level at same frequency.These Notes has been made by me after watching NPTEL lectures given by Dr. Debaprasad Kastha from IIT Kharagpur.You can download it topic wise.

Download notes,take a printout then watch NPTEL lecture and then go through these notes. No need to write anything, everything is written in notes. It will save your time.
